I am trying to get wp-display files to show the files from Amazon but when syncing I am getting an error that says:
The authorization mechanism you have provided is not supported. Please use AWS4-HMAC-SHA256.
It looks like the SDK used is from 2012 and doesn’t support v4 auth that is defaulted on the new buckets in the US. Any chance you are going to update it to the newer SDK so this works with AWS4-HMAC-SHA256?
It is really strange, Are you using latest version 2.0.4 if not please update your plugin to the latest version and your issue will be resolved. I checked this issue at our end and there is no error we are getting. Authorization successfully happens with AWS. It would be great if you provide me wp-admin details so we can check it at your end also.
